so today i went to go start my bike. choke fully on. the rpm's usually start off low and get higher. but today the rpms never went up. instead the exhaust started spritzing gas and the engine slowly cut out. i attempted to start it back up but it wouldnt even sputter. i guess its flooded but whats wrong with my carbs to cause this problem. they were working great yesterday

 

I'm no expert, but it sounds like an ignition issue to me... but what's the story leading up to this? Did the bike sit for a while? Did it happen out of nowhere? Did a black cat cross your path?

 

im not sure about a black cat but it did happen out of no where. the bike ran perfect the other day. i rode it from CT back to RI without any troubles. then i fired her up yesterday morning to go to class and she slowly died. she definently flooded herself and i cant get her to even sputter anymore. i think the plugs are now fouled.

 

whens the last time you cleaned the carbs?

 

the carbs were rebuilt last month. but i found out the problem..... i went to rayzees motorcycle shop and a mechanic took one look at my bike, rev'd it and new exactly what the problem is.

he rev'd my bike to around 6-7k and smoke came out the exhaust. i never noticed this before since i dont go reving my bike when im not moving. the guy said the cylinder rings are toast and oil is getting past them. and the engine is getting blow back sending the oil smoke to the carbs and clogging my air filter and causing my engine to flood. basically life sucks right now

 

****ING hunk of **** CBR forum just ate my post and said it was too short!


Anyways, the motors don't typically die. You can do a compression test yourself. If one tests low, spray oil in the cylinder (WD-40 is fine too) and then manually advance the motor and check compression on that cylinder. The oil will seat with the rings and cause the cylinder to retain compression, provided the rings ARE in fact bad. If all of the above checks out, yeah you got bad rings. Time to learn about working on motors
